It appears that their regassing machine wasnt working properly originally and didnt give the full charge. When I took it back it wasnt chilling anything. I'm told there are no leaks and is now fully charged. Doesnt explain why I lost the gas in the first place though.
At least they admitted it and didnt try to recharge me.
Jazzy, I dont understand even if the refrigerant is a blend why it has to be fully evacuated before you can put more, presumably of the same blend back in???
